Recommendations for Preamp for Balanced SPL Performer s800


Hello,
I just received the SPL Performer s800 Balanced Power amp and was looking to find a nice match in a preamp for it. Thinking maybe a nice tube preamp would compliment it. Was hoping you all could possibly give me some recommendations?
